Aah ok! I checked and it is seated correctly and if i push the operating lever with my (brass) tweezers it resets properly. I think I just got really unlucky and managed to find the only malfuctioning reset operating lever ever. Thanks for the idea!

Hi guys!
Material sciences engineering student here and I've been into watchmaking (or repairing to be more precise) as a hobby over the last 2-3 years. I've been servicing watches very actively and have come across most types of watches ranging from IWC ingenieur 666AD to the ubiquitos 7750 a multitude of times. I started out with cheap tools just like nearly everyone else but noticed it really isn't worth the hassle and I now have an extensive collection of swiss tools and proper cleaning machine too!
Hope everyone is having a nice day.
Regards,
Antti

Hi!
I am having problems resetting the chronograph after servicing my IWC porsche design. This is far from my first rodeo on the 7750 and I consider myself quite competent with it.
The problem lies in the reset operating lever. The pusher stem pushes too low on the reset lever and instead of resetting the chronograph it just flexes inwards. If I use pegwood or a movement holder, it resets correctly because it pushes higher up on the operating lever.
I was thinking I should either bend the operating lever slightly outwards so it would hopefully overcome the flexing or loosen the cam jumper so it doesnt take as much force to reset. Any ideas and tips would be greatly appreciated if anyone has had a similar issue before, thanks!
Best regards,
